An unmentioned subcategory is words that that sound or look like taboo words, but are actually unrelated: "niggardly", "Gaylord", "fag" as in cigarette (from "fag end", unrelated to "faggot"), etc.

[moonchild]

A 'faggot' is also a bundle of wood.

[dustintrex]

Yes, but this appears to be the origin of the pejorative: bundle of sticks -> an old woman collecting sticks -> a man who acts like an old woman -> homosexual.

[madaxe_again]

It’s also a bundle of anything - including tobacco, which is where fag comes from. Derived from the same root as “fasces” and therefore fascism.
